My requirement is to parse the xml and generate the attributes depending on the field names specified by the user.For eg, if the user specifies the field name as 'name|rno' , the parser should parse the xml and return a tuple containing name and rno.

I am using XML Loader to parse the xml up to student and then have written a java UDF to parse the student xml.I tried to define a parameterized constructor in my java UDF class wherein I pass the columns/ attributes to be parsed.I have then overridden the outputSchema(Schema input) method , in which I fetch the column names and add new field schema.

However this does not work the way expected. Is there any way of getting this done?DISCLAIMER=========This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
